I got a set of custom 6.0 ls diamond pistons with a block I got awhile back. If I did the compression calculator right should be around 8.8-8.9 with 60cc heads. I have set of 243’s that are 60cc. Question is that too low for a turbo truck. I have two two turbos, 76mm and a s480. It will be a street/strip truck with Holley termx. I attached the piston specs, thanks

 

Whats your power goal and what fuel do you intend to run it on most of the time?

 

Pump gas if possible, truck already has 4l80 with 3600 circle d, horsepower I guess be limited to to the fuel, I like to see 600+.

 

Pump 91, 93, or E85?

That low of compression should allow some tuning forgiveness and maybe a little more PSI on your typical 91/93.

 

I got access to 93 and got e85 for another project I’m working on. Just curious if they worth putting in a 6.0 with rods.

 

With enough boost and crank case venting you will hit your 600

 

While 9.5 would give more out of boost torque and drivability 8.8-8.9 will allow you to crank it up more on pump 93. Ultimately more boost = more power. If that's your goal just run it! If you want more compression though use some 706's instead but you'll have to run less boost, timing etc or more octane via meth or E.
